The Top Ten

1RayquazaRayquaza is a Legendary Pokémon species in Nintendo and Game Freak's Pokémon franchise. It lives in the ozone layer, and frequently stops battles with Kyogre and Groudon, two other Legendaries.

He helps stop battles between Groudon and Kyogre and he protects the Earth from any threats within the domain of the ozone layer. I don't see how he's evil. Plus, he only misunderstood Deoxys in the Destiny Deoxys movie. - ModernSpongeBobSucks

2ArceusArceus is a legendary Pokémon from the Pókemon series. He first appeared in the 18th Pokémon movie alongside other Legendary Pokémon.

The poor Arceus had to endure betrayal and abuse in The Jewel of Life... - ModernSpongeBobSucks

3NihilegoNihilego is a dual-type Rock/Poison Pokémon introduced in Generation VII. It is not known to evolve into or from any other Pokémon. It is one of the Ultra Beasts and is known by code name UB-01 Symbiont.

The very creature that intoxicated Lusamine's mind and sanity... - ModernSpongeBobSucks

4DarkraiDarkrai is a legendary Pokemon developed by Game Freak. The only way to get this Pokemon was through two events, only one in the United States.

His only heroic role was in Rise of Darkrai. In other games, he's given a more antagonistic role in Explorers of Time, Darkness and Sky and PokePark 2. - ModernSpongeBobSucks

5Zygarde

Ah, come on. He didn't do anything wrong. Poor trio mediator had to be demoted to extra and was never given a proper game treatment. Plus, he was only being used in the wrong hands by Team Flare in the XYZ anime. - ModernSpongeBobSucks

He is dragon/ground steals zekrom's place in the game called "pokemon X and Y" - mewtwo1

6Phione

It's only an inferior breed of Manaphy that you get when breeding Manaphy with Ditto. Then again, THAT would be what makes it evil, if you know what I mean. - ModernSpongeBobSucks

HE KILLS MANAPHY! - mewtwo1

7Kyogre

Not really evil. It's just the nature of Groudon and Kyogre that has them duking out over land and sea respectively whenever they come into contact with each other. Thank Arceus for Rayquaza stepping in at every feud between them. - ModernSpongeBobSucks
